Application filed December 26, 1913, Serial No. 808,833. "Renewed June \24, 1915'. Serial No. 36,151.

To all whom it may concern).

Be it known that I, OLIVER A. Mnynns, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Devices for In-' troducing Air to the Carbureted- Mixture for an Internal-Combustion Engine, of

which the following is a full,clear, and ex-' act description.

This invention relates to a device for in-' troducing air into the manifold of aninternal combustion engine, between the intake valves for the'engine and the carbw reter.

Generally speaking, the invention comprises the elements and combinations thereof" set forth in the accompanying claims.

Reference should be had to the accompanying drawings forming a part of this specification, in which Figure 1. shows 1n elevation the, manifold of an engine with the device of my inventlon mounted thereon, and a' heating device by which the air passing through the device of my invention is priorly heated. Fig. 2 1s a sectional elevation'of the device of my 1nvention. Fig. '3' is a section on the line 3-3 of Fig. 2; and Fig. 4 is'a cross section'showing a modified form of my device.

For some time it has been generally recogp p nized that it is advantageous to introduce air into the fuel mixture before it passes into of the car neglects to shut off his air valve when the engine is stopped and subsequently endeavors to start the engine with the air valve open, the engine will probably not respond, due to an excess of air inthe gas mixture.

My device works entirely automatically,

so that no attention need be given to the device, after it is lnstalled.

As illustrative 5r he manner in which my device is applie t ere is shown in Fig. 1 at 1 the manifol of an engine, and secured in this manifold istlli tron generally represented at 2.- Connected with the device 2 is a flexible hose 3, which may be secured to the device 2 in any desired.' manner, and for thepurpose I use pins such as shown at4, carried by the hose, which are caused to enter right angle grooves, as at 2*, In my device, the groove and pin forming a bayonet joint and thereby securely. holding 'the .hose 3.

Around the exhaust pipe from the engine, whlch is represented at 5, I would place a chambered member 6, -this n'1ember being split. and held together in a'nysuitable man nor, as by a bolt such as represented at 7. As will be seen from'the drawing, the casingis hollow and is provided with one or more inlet ports by which air may enter intothe casing and coming into contact with the exhaust pipe, the air will be-heated.v This casing is pmvided'with a neck 8 which has formed therein a groove 8*, the groove cooperating with a pin 9, which is carried by e device of my inven-.

the pipe 3, the two forming a bayonet joint. Q

It 'will be understood that the description ivith'respect to the groove 8 and the pin 9 is duplicated upon the opposite side of the It will be obvious that as the pistons within the cylinders of the engineare reciprocating and producing a suction, this suction will operate to draw air throughthe sleeve 6, pipe?) and to the device of my invention represented at 2.' v I In Figs. .2 and 3 and it is illustrated the particular device for controlling the 'rate of flow of air which is delivered to the manifold.

The device comprises a two-part casing, represented at 10 and 11,-these'being secured together, preferably by a screw thread engagement. The portion 10 of the device is preferably cylindricalin form, and at one end is provided with a hollow exit neck represented at 10, the diameter of the inside of the exit neck being less than the internal diameter of the main portion 10, so that a shelf isformed at the end of the neck and this shelf supports a series of layers of fo'raminous -material and fibrous'material.

The foraminous material, -which I employ, 1s screendisks, of small mesh, and these disks are preferably circular, and of a diameter which is slightly less than the internal diameterof the portion 10. The

fibrous material which I employ is preferopening into the manifold 1.

' cally taken care of. .That is to say,

justed ably cloth and is likewise-in the form of disks. Tn placing this foraminous and fibrous material. within the portion 10, 'I

superimpose a. number of disks of, screen material, as represented atf12. Then I place.

a layer of fibrous material or cloth, as indicated at 13. Upon this is placed a second layer or pile. of screen disks, the same as those described at 12, and so on in succession 1 use astac'k' or pile of disks of screen material, which'stacks are separated by-a layer of fabric- When'this material has been placed within the receptacle 10, the portion 11 is screwed'in and will'hold-the screen material and the cloth material in place.

- The end of the neck portion 10 is screw threaded, and is adapted to cooperate with screw threads formed in the wall of an screw threads the. portion 10 carries a cylindrical drum 1% formed of for'aminous or screen material, and extends .wlthln the manifold 1. This cylindrical portion 14 serves to cause the added'air and the fuel mixture to be thoroughly mixed With each other.

The action of my device seems to be as follows: The suction produced by the engine when running tends to cause a movement of the disks in .such a manner as will produce a movement of the disks in accordance'with the suction produced by the engine when running. 'The position of the disks will be changed in accordance with the variation in the suction produced, and

this movement cf the disks will control the quantity of this invention. The air apparently passes around the edges ofthe disks in greater quantities than it does through the body of the disks itself, and the disks move in a manner as to permitincreased quantities of air to be supplied to-the engine as speed the higher speeds Below the v of air passing through the device" found that the engine works much more efliciently. That isto say, less gasolene is required to maintain a given speed of the engine, when using this device, than is the case when the same speed of the engine is maintained without using the device of my lnvention.

It may be found desirable to formgrooves such as indicated'at 15 in Fig. 4, in the inner wall of the casing 10',- to thereby admit a greater amount of air than in the present arrangement. This I consider entirely within-the spirit .of my invention.
